List of Total Radioactive Elements in The World
Doodlebrary
- There are over 3,000 known isotopes of elements, and many of them are radioactive to some extent.
- However, the term “radioactive elements” typically refers to elements whose most stable isotopes are radioactive.
- Here is a list of some of the most well-known radioactive elements:
- Uranium (U) – Uranium-235 (U-235) and Uranium-238 (U-238) are the most common radioactive isotopes of uranium.
- Thorium (Th) – Thorium-232 (Th-232) is the most stable and commonly found radioactive isotope of thorium.
- Radium (Ra) – Radium-226 (Ra-226) is the most famous radioactive isotope of radium.
- Polonium (Po) – Polonium-210 (Po-210) is a well-known radioactive isotope.
- Radon (Rn) – Radon-222 (Rn-222) is a naturally occurring radioactive gas.
- Plutonium (Pu) – Plutonium-239 (Pu-239) is a fissile material used in nuclear reactors and weapons.
- Cesium (Cs) – Cesium-137 (Cs-137) is a radioactive isotope often produced in nuclear accidents.
- Strontium (Sr) – Strontium-90 (Sr-90) is a radioactive isotope produced in nuclear fission.
- Promethium (Pm) – Promethium-145 (Pm-145) is a radioactive isotope often used in nuclear batteries.
- Technetium (Tc) – Technetium-98m (Tc-98m) is a widely used radioactive isotope in medical imaging.
- These are just a few examples of radioactive elements and their most common radioactive isotopes.
- Many other elements have radioactive isotopes, but they may not be as well-known or commonly encountered.
- Additionally, new isotopes are continually discovered and studied in the fields of nuclear physics and chemistry.
